* Use typeof(console) to prevent IE 7 error

When using directly console !== undefined, older IE versions
throw an error as they're actually tring to access an undefined
value. Use globally supported typeof(console) !== 'undefined'.

Changed typeof(<var>) to typeof <var> as it's not a function

Thanks @sgiehl

* Change other occurences of console !== undefined

* JSLint: Remove console available global as it is not in IE7 and other older browsers

* Minified piwik.js

* JSlint validation

* Minified files after merging 3.x-dev
